Abstract

Problem statement: This study described the design of a 3-phase AC Induction Motor (ACIM) vector control drive with position encoder coupled to the motor shaft. Approach: It was based on free scale's (Motorola's) 68k micro processor devices. Although the free scale 56F80x (56800 core) and 56F8300 (56800E core) families were well-suited for digital motor control and offer all things was needed, but we decided to realize a complete vector controller with a powerful 68k processor. Results: Obviously all 680X0 and many 683XX can overcome this task very easily, but we decided 68332 for time consuming because it combines high-performance data manipulation capabilities with powerful peripheral subsystems. All software and hardware was based on Peter J. Pinewski's nice research from Motorola. Conclusion: In this study the overall software algorithm and in two fellow papers the hardware schematics and performance will be described respectively.
